气候变化加速了北极永久冻土解冻,使加拿大北部和西伯利亚的野火增加。 Climate change accelerates Arctic permafrost thawing, increasing wildfires in northern Canada and Siberia.
《自然通信》的一项研究警告说,气候变化将加速北极和亚北极的永久冻土解冻,导致加拿大北部和西伯利亚的野火增加。 A study in Nature Communications warns that climate change will accelerate permafrost thawing in the Arctic and Subarctic, leading to increased wildfires in northern Canada and Siberia. 先进的气候模型预测,到21世纪中下半叶,土壤湿度和火灾强度将发生重大变化。 Advanced climate models predict significant shifts in soil moisture and fire intensity by the mid to late 21st century. 由于被解冻的永久冻土释放了碳,支持了更大的植被增长,必须采取紧急行动,应对这些不断升级的环境威胁。 As thawed permafrost releases carbon and supports greater vegetation growth, urgent action is necessary to address these escalating environmental threats.
